Is there anything specific, because I'm going to explode if I start from the beginning. But I guess the general stuff first: My sona has some kind of plasmatic energy core where the heart should be (not born with it), that gives her shadow abilities and can transform into a Phantom Haxorus.

The idea of the phantom came from a joke AU where I did take over the world and wanted something cool to make it believable that an idiot like me pulled it off It was your typical cartoon villain stuff, but funny. I kept the abilities when I joined miiverse in 2014 to make my character interesting
